I wrote earlier this week about the AR platform and how much it can be reconfigured with seemingly limitless possibilities and there is really not other rifle on the market with such a versatile design out there.

AR-15

AR-15

For years I have had my own views and opinions on the M-16/M-4/AR-15 platform and the .223 Remington/5.56NATO rounds and have shot a fair number of different AR-15s.

I like the style of the weapon the look of the weapon and the ease of use.

Over the years I have seen how interchangeable the whole weapon system is and how a simple push of two pins can change the weapon from firing a .223 to a .50 BMG or a change of the bolt can make it fire a .22LR.

The AR platform can be configured to a good number of different calibers such as: .20 Practical, 22LR, 5.45×39, .223, 5.56NATO, 6.5mm Grendel, 6.8 SPC 7mm TCU, .300 Whisper, .300 Blackout, .338 Lapua, .40 S&W,  10mm, .45 ACP, .450 Bushmaster, .458 Socom,
.499 LWR, .50 Beowulf,  .50 BMG, 7.62×39 just to name a few

The upper can be changed to make the weapon a shotgun, a belt-fed weapon, fire pistol rounds or just be reconfigured into a short pistol style weapon.

The versatility that the AR platform offers to the shooter is almost limitless and with more and more companies designing uppers and various other parts the next few years will make it limitless.

Kel Tec PLR-16

Kel Tec PLR-16

Calibers: .223 Remington
Weight unloaded: 3.2lbs
Length: 18.5″
Barrel length: 9.2″
Twist: 1:9″
Magazine: AR-15 compatible detachable box magazines (STANAG Magazines)
Trigger pull: 5.5-7.5lbs
Action: Gas-operated
Muzzle velocity: 2600fps
Effective range: 400 m

The Kel-Tec PLR-16 (Pistol, Long Range) gives the shooter the a .223 rifle in a compact pistol/PDW design.

This weapon is small enough to be carried in a leg holster. The nice thing about the Kel-Tec is it lets the shooter use the same magazine in both an AR and this gun so you don’t have to buy all new magazines if you want more than what comes with the weapon.

plr-16

The PLR-16 uses both the multi-lug rotating bolt design and breech-locking system similar to the AR-15 with a gas piston system like that of the AK-47 and M-14.

Specs

Caliber: .458 SOCOM
Barrel: 16” Chrome Moly Bull Barrel, 1:14 R Twist
Action: Semi-Auto AR Platform
Overall Length: 36”
Weight (empty): 7.6 pounds
Magazine: Standard .223 AR-15 Mags

SOCOM (Special Operations COMmand) contracted out for a new project which was brought on by a lack of power that the 5.56NATO cartridge has in the M4 and the M16.
SOCOM set a number of specific requirements for this new weapons system such as that the round must fit the standard M4 – M16 Platform and standard magazine and be capable of firing heavy-for-caliber projectiles at subsonic velocity using suppressors.

Marty ter Weeme, founder of Teppo Jutsu LLC. designed the cartridge in 2000 and Tony Rumore of Tromix, Inc was contracted to build the first .458 SOCOM rifle for use in February 2001.

In the developments phases, there were various other cartridges that were considered and proposed to the project sponsor, but rejected as not meeting all the requirements. The cartridges considered were 7.62x39mm, 9x39mm Grom, .450 Bushmaster, and .50 Action Express.

The .458 SOCOM uses the standard AR mag but due to it size does not allow for double stacking the rounds and subsequently only lets the mag hold a fraction of the rounds.

  • 10 rounds Magazine designed for .223 will hold 3 rounds of .458 SOCOM
  • 20 rounds Magazine designed for .223 will hold 7 rounds of .458 SOCOM
  • 30 rounds Magazine designed for.223 will hold 10 rounds of .458 SOCOM
  • 40 rounds Magazine designed for.223 will hold 13 rounds of .458 SOCOM
  • The 90-round .223 drum can hold as many as 33-36 rounds of .458 SOCOM
  • The 100 round beta mag will not work.

The AR-15 platform chambered in the .458 SOCOM gives a hunter a lightweight rifle with in  heavy caliber  that is durable and well suited for large game hunting.

Bushmaster ACR

Bushmaster ACR

bushmaster-remington-acr

I know I am going to catch some flack from writing about the ACR before I write about the FN-SCAR but I’m okay with that because no one requested the SCAR.

SPECS

Caliber: 5.56 – 6.8 SPC II
Barrel: 10.5” – 14.5” – 16.5”
Trigger: Standard AR/M-16 trigger, 4.5 – 6lbs, Match trigger available
Magazine: Accepts MagPul PMAG and Mil-Spec M-16
Weight: 14.5 Weapon, Base rifle – 7lbs 14oz, Loaded w/ suppressor – 9lb 13oz
Length: 14.5 Weapon, W/o Suppressor, Stock folded – 25.75”, W/o Suppressor, Stock deployed – 32.625”, W/o Suppressor, Stock extended – 35.5”

Bushmaster has announced plans to make the ACR in 6.8 SPC and 7.62x39mm.

The ACR stands for Adaptive Combat Rifle and is easy to interchange the caliber of the rounds this rifle shoots with THREE simple changes, the barrel, the bolt carrier, and the magazine.

remington_acr

This weapon has a few variations such as barrel lengths and calibers, the color schemes, Stock made of polymer or metal, Lower receiver made of polymer or metal.

This system truly lives up to its name as an adaptive rifle for the end user.

(Update) On October 15, 2010 Bushmaster issued a recall of all ACR rifles instructing users to “Please immediately discontinue the use of your ACR rifle” along with instructions to contact customer support for an RMA. Bushmaster stated that the recall was issued due to “a possible firearms performance issue that may develop with a small number of ACR rifles” and goes on to state that “Bushmaster discovered a design flaw which could result in multiple rounds firing continuously when the trigger is pulled”. Bushmaster has stated that it will cover all of the costs associated with the repairs to the recalled rifles [wiki]

Promag magazine vise block

PM123-2T

Here is something I think is pretty nice if you ever have to work on your AR or if you are planning on building an AR. The vise block lets you work on your AR locked in a vise so your gun doesn’t move.

The block is made with a durable black polymer so it will hold up to years of use and is designed after the standard AR-15 .223/5.56NATO magazine and just slips into the mag well and locks in using the rifle’s magazine catch.

This is the new Sig Sauer 716. this rifle is designed after the AR-10 rifle and they are making 4 sizes of this Rifle all chambered in .308 Win / 7.62NATO.

They are making Semi-auto version of all four rifles for purchase in the civilian market.
The release dated has yet to be announced.

I will be excited when the I can read the reviews of this rifle after it has been fielded. This rifle is against some heavy hitters such as the M110 or the AR-10.

AR Magazine Lock

AR Magazine Lock

AR_mag_vault_w-key_3

I was talking to someone the other night about the AR platform and they were asking my take on the rifle and how far it has come since its introduction into the US military in 1963 and long story short he asked about locking the gun up and after talking a bit about a gun safe he asked about locking the weapon itself up so it couldn’t be loaded with a magazine.

Now this got me thinking about the locks on the market I had seen and most of the ones I had looked at were cable locks and so I figured I would look and see what was out there for the AR and this was one I liked for the shear fact it slides into the mag well and also blocks the barrel from loading of a round.

mag_vault_in-AR_view2_2

This is the GunVault AR MagVault Rifle Lock. the price online isn’t bad and I like that is a bright orange so it is clearly visible when the weapon is just sitting there.

Question…

Question…

I have a question
of all of the AR-15 weapon system platform that are made in the world… who do YOU like the best and why?

I have shot a round or two through some ARs and and I know from what I have shot which I like but I want to hear from you! leave us a comment about the gun(s)

It doesn’t have to be an AR-15 it can just be a rifle designed like the AR. I know Remington makes an AR platform rifle and calls it: Auto loading Model R-15 (or R-25 for the .308 chambered rifle)

I was doing my late night surfing when I came across this AR-15 magazine
cdmag_retouch 

CAA has come out with what they are calling the “Countdown Magazine”
This gives the shooter a count of how many rounds he has left. The indicator shows in three colors Green (30-21), Yellow (20-11) and Red (10-0) so you know you are almost out.  This is a Polymer Magazine with Stainless Steel Spring and Anti-Tilt Follower, for a more reliable Mag.

cdmag_gun

This will run you about $10 bucks more than the leading brand 30 round polymer magazines. but the payoff is the ability to know when you have only 1 round left or still have 3. I like gadgets and toys so that might be one of the reasons I would get this.
